Description

testo 526 is the differential pressure meter for industrial applications. Critical processes can be measured and monitored efficiently with an accuracy of up to 0.05% of the full-scale value.

  • Temp. compensated differential pressure sensor, 0 to 2000 hPa, integrated in instrument
  • Available in 2 accuracy classes: 0.1% / 0.05% of full-scale value
  • Measures leakage rate (pressure drop per time)
  • Checks drop in pressure in containers, cables etc. via the built-in test menu
  • 2 probe sockets to connect additional probes for measuring pressure, temperature, current/voltage
